1. A method comprising:

  • in response to a write operation to a region of a plurality of regions of a storage area, incrementing a respective counter of a plurality of counters;

    in response to an acknowledgement that the write operation to the region is received at a replication storage area, decrementing the respective counter for the region;

    identifying a set of unreplicated write operations from the plurality of counters, wherein a non-zero counter value of the plurality of counters indicates a number of unreplicated write operations for the region; and

    examining a spatial distribution of the set of unreplicated write operations among the respective regions to select a synchronization method.
